The invention provides a brake-by-wire system with redundant backup braking and a control method, and belongs to the field of vehicle braking. A cavity with a single inner cavity is arranged, the cavity is connected with a first isolation electromagnetic valve and a second isolation electromagnetic valve which are connected in series, the first isolation electromagnetic valve and the second isolation electromagnetic valve are connected with a braking loop a, and the braking loop a is connected with two wheels; the first isolation electromagnetic valve and the second isolation electromagnetic valve are controlled through the first ECU and the second ECU respectively and are controlled independently, in this way, the effectiveness is improved through the cavity with the single inner cavity, the pressure of the main cylinder module cannot reach the wheels only under the condition that the two isolation electromagnetic valves connected in series fail, the braking effectiveness is greatly improved, and the braking efficiency is greatly improved. And the first electric control braking module and the second electric control braking module are matched to brake the wheels, so that the safety of the braking system is ensured, and the problem of low effectiveness is solved.
本发明提供一种带冗余备份制动的线控制动系统及控制方法,属于车辆制动领域,通过设置单内腔的腔体,腔体连接串联的隔离电磁阀一和隔离电磁阀二,隔离电磁阀一和隔离电磁阀二与制动回路a相连,制动回路a连接两个车轮,隔离电磁阀一和隔离电磁阀二分别通过ECU一和ECU二控制,单独进行控制,这样采用单内腔的腔体使得有效性提高,两个串联的隔离电磁阀只有在两个都失效这一种情况下才会导致主缸模块的压力到不了车轮,大大提升了制动的有效性,再配合第一电控制动模块和第二电控制动模块对车轮进行制动,保证了制动系统的安全性,解决了有效性不高的问题。
